So i just finished rebuilding my first engine, its a 1984 Chevy 305, don't hate me for that, haha. Anyway i am running an 11:1 compression ratio and a mild cam, how much horse power can i expect to get out of it?

Cam specs:

Intake Duration at 050 inch Lift: 234

Exhaust Duration at 050 inch Lift: 244

Advertised Intake Duration: 292

Advertised Exhaust Duration: 302.

Intake Valve Lift with Factory Rocker Arm Ratio: 0.488 in.

Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.510 in.

Lobe Separation Angle: 114

I am also using an intake and Quadrajet carb off a late 70s Chevy 400

I just got it mounted on the break-in stand and will be firing it up one day soon!

you need a flow bench.The bore size has to be adjusted to match your engine.The tech will take readings at .3,.4,.5 inches of lift. with near stock parts you will get moderate improvements over stock ratings

The intake and carb were off a late 70s Chevy 400 engine, right now the engine is on a break-in stand and as far as exhaust all i have on it is headers, they have 3in outlets, thats all i know about them, i am borrowing them

We don't hate ya. Congratulations on your first engine. Now you can spend the rest of your life trying to build your "BEST" engine.

Horsepower? Well..... not much i'm afraid.
